do you cut off feeding nutrients 2weeks prior to harvest or feed all the way up until harvest then flush it ?

i am running the shogun samurai coco nutrients at it has a additive made for the 2nd to last week of flower its called dragon force then after that 1 week plain water im just confused on when i should begin my 2week flush would i checkout my trichomes and overall qaulity and if trichomes are 70%amber 30%milky i should begin the 2week flush phase? with 1 week being just dragon force then the last week water?

ive attached a image of the feed chart so you can have a better understanding of what i see

I believe that is true for organically growing but when using synthetic nutrients it’s a must to flush no? To get rid off all salts in medium and lockout nutrients being available to the plant for better overall product? Your point is fair tho and could work amazing but for this time (my first time) I will atleast flush for 1 week 3days the least

I just wanted opinions or advice from experienced growers who grow synthetic in coco as to when they flush and how long for 😊

Thankyou tho buddy!

Flushing is a myth. 2 weeks before harvest cut nutes back 25%. Week before harvest, cut back another 25%.

Do you grow in coco using synthetic nutrients.?

Have you done this technique and how was the overall product ?

I dont use coco, but I do use an inert medium/Sphagnum Moss. Promix BX. Ive never flushed, in 47 years. And I use chemicals.

I've done side by side with clones and no difference I can smell or taste with flush so I chop when the plant is ready.

so you feed nutes all the way up until you cut never watering plain water towards the end.?

Unless one force feeds a plant, the plant, will only uptake what it needs to survive. No more, no less.
The main thing is towards the end, when the plant starts using less water, also means its food needs will also go down, but it makes no sense to starve your plant, when there are still metabolic processes going on. Often, on the last watering, I will water with water only, but by that time, the plant has done, what its going to do, and if the plant really needs anything, there will still be a small amount of fert, left in the medium. But unless the medium is overloaded with fert, the plant will only use whats necessary to survive. I always try and use the Least amount of fertilizer, but, also enough to keep them happy, healthy, and growing as fast as possible, and using as much water as possible. Overfert, is also a good way to make some plants hermi.

It's been a few months since you posted this question; how did your harvest turn out?

I am in the final few weeks for my first grow in coco coir using General Hydroponics nutrients, which is going much better than prior attempts with soil (plants are healthier), but I also question when to stop giving them nutes.

Are you using General Hydroponics Flora Series?

Here is a study on flushing, test showed that best flavor and smoothest hit was from plants with 0 days of flushing.

This is the chart I use when using Flora, it shows a flush the last week but I don't do that. My plants are green at harvest.

Y.E.S! This is how it's done, what works for YOU, not anyone else😉 and then you can tell folks "Hey A, B, C, D worked/didn't work for ME. Encourage others to do their own research😘 This is how we eliminate Bull Shit🥰

I've been growing in coco for the past 5 years. I've tried so many different configurations of nutrients using Master Blend I can honestly tell you this: you wanna flush? Flush. You find the plant ready for harvest and you havesnt flushed? You go ahead and harvest. It doesn't matter, at least to me and my taste buds. I do not taste any difference, never ever have. Most people just repeat what they've heard.

I gotta take a moment and promote Master Blend here and no, I do not make a penny or free anything, not even a reach around) from Master Blend or their middlemen sellers. It's basically the same shit you're buying in the fancy bottles mixed with distilled water and packaging. There's little difference except I'm not buying the water. I make a 1 gallon concentrate that will mix 32 gallons of water into nutrient water and I can adjust that to fit herbs to trees.

But hey, those bottles have cute pictures on 'em😉

Appreciate the recommendation on Master Blend. I do like the coco over soil but being my first attempt in just coir, my flowers in week 9 are telling me there is definitely room for improvement. I like the GH better than Fox Farms (with the cute labels) though the three part measuring is cumbersome for hand watering. Recommendations from more seasoned farmers are welcome, so thanks!

To flush or not to flush, perhaps the purging is more psychological for the grower than biological for the plants, as far as I can tell from reading these thread comments.
